Broadly, limnology and biogeochemistry are my interests and favorite research field. For the pursuit of Ph.D., my research focuses on the study of dynamics of dissolved organic matter (DOM) in aquatic and terrestrial ecosystems. For the characterization of DOM, stable carbon and sulfur (S) isotopes and stoichiometry have been analyzed in the Hubbard Brook Ecosystem Forest, NH and Arbutus Lake watershed, NY. Also I expect that stable S isotope value in DOM helps to understand imbalance of S in the forest ecosystem, e.g., HBEF.
